(l. = lover), (u. = uncle). The Tower Princedom is a sort of honorary spinoff princedom for Taracis' favorite young half-brother, who is now an old man. I imagine that besides Scroll and Sea, these side princedoms are often split off for favored relatives and then reincorporated into Scroll lands after a period of time.
The situation with the Sea Princedom is utter debauchery: The Sea Prince's old wife died but not before leaving him with one adult son. He took a new young wife, younger than his son, who is her stepson's mistress in an attempt to secure her influence. The son, meanwhile, has his own wife who is copulating with the Prince (her father in law) out of a desire for revenge.
Also I changed his name to Karynir now.
